You can append that in lilo.conf - append=/dev/lp0 0x378,7,3 or something - check with others before doing that, because I'm not sure I'm right about the syntax. The other thing is that the printer doesn't *need* to use DMA - most use polling by default and work just fine. It's a question of CPU overhead, AFAIK. Some newer printers do use a DMA setting for faster results, but I don't know if yours is one of these. When you cat foo.txt > /dev/lp0, what happens? Does it attempt to print, but spit out a blank page, or does it just fail silently. If it's the first, it may be at the filter level. If it's the second, I'm not sure where he problem is. It may take more digging. Good luck, Steve
